Tenants' ESB bills

It was €300 and DD the last time I took over an ESB account. €300 is returned after 12 months good behaviour.

You sure that wasn't an error on your part to supply the 2?
See the first link i posted in a previous post above.

It states yoe can avoid the €300 by opening up a DD.
 

Has anyone got any information on this ESB credit?
 
 
you may wish to consider getting esb to fit pre-payment meter, the tenants simply buy tokens from there local pay point outlet ,ie (credit union) etc. No tokens = no electric
